DUM PING DEVICE FOR AERIAL TRAMWAYS.

SPECIFICATION forming part of Letters Patent No. 738,308, datedSeptember 8, 1903.

Application filed January I9, 1903. Serial No. 139,612. (No model.)

To all whom it may concern:

Be it k'nownthat I, CHRISTOPHER T. FINLAY- soN, acitizen of the UnitedStates of America, residing at Denver, in the county of Denver and Stateof Colorado, have invented certain new and useful Improvements inDumping Devices foinAerial-\Vire-Rope Tramways; and I do declare thefollowingto be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in dumping devices for aerialwire-rope tramways.

Aerial wire-rope trainways consist of either one or two ropes stretchedbetween two points called terminals above the ground upon suitabletowers and may vary in length from a few hundred feet to several miles.are especially adapted to convey ore, coal, provisions, and othermaterial down and up mountainous countries, over gulches and rivers.Where only one rope is used,the tramway is called a sin glerope system.lVhere two ropes are used,the system is called the doublerope system.There are two types of the double-rope syste1none called the overheadsystem, in which the traction-rope is positioned above the track-rope,and the other called the depending system, in which the traction-rope isplaced below the track-rope. In the singlerope system the traction-ropeis used to convey and support the bucket or carrier. In the double-ropesystem the traction-rope is used to convey or propel the trolley andbuckets or carrier, and the trackrope supports a trolley which supportsthe bucket or carrier, thetrolley running on the track-rope Theterminals are timber structures which support a large sheave orropegripping sheavewheel, around which the tractionrope runs. Thetraction-rope is an endless running rope. The track-ropes are stationary ropes that at the terminals generally merge into metal railsortracks curved around the ends of the terminals, so that a continuoustrackis formed around the terminals and from end to end of thetram-line. The buck- They ets or carriers are loaded at one end andunloaded at the opposite end, and loading or unloading stations can beinserted wherever necessary in the various systems in use.

The objects of my invention are, first to provide a dumping device thatcan be used on either the double-rope or single-rope system of wire-ropetramways; second, to provide a dumpin g device that is especially ad apted to the two types of double-rope tramways known as the overhead"-system, in which the traction'rope is placed above the trackrope, andalso to the depending system, in which the traction-rope is placed belowthe track-rope,and also to the system in which one rope is used both asa traction-rope and as a bucket or carrier supporting rope; third, toprovide means for automatically dumping a bucket at any desired pointsof a tramwayline or at any desired point at either side of a tramwayterminal; fourth, to provide means for automatically dumping a movingbucket or carrier at any desired point at either side of a terminal orat any desired point in the length of the tram -line; fifth, to providemeans for dumping a standing or stationary bucket or carrier at anypoint at either side of a terminal or at any point in the length of atram-line; sixth, to provide means for automatically or manually causinga bucket or carrier to pass at will. the dumping-stations or theterminals; seventh, to provide a simple and positive mechanism fordumping a bucket or carrier on any of the Wire rope tramway systems incommon use. I attain these objects bythe mechanism described in theaccompanying drawings, in which Figure 1 is a side elevation of afragment of a terminal of a wire-rope tramway, showing the applicationof my automatic dumping device to it. Fig. 2 is a cross-section of Fig.1 on line 2 2. Fig. 3 is a sectional plan view of Fig. 1. Fig. 4 is aperspective view of the manually-operating mechanism for moving thebucket or carrier dumping mechanism out of the path of a running bucketor carrier, so that it may pass the dumping-station. Fig. 5 is aperspective view of the track-yoke. Fig. 6 is a side elevation ofmechanism I employ for dumping a standing bucket. Fig. 7 is an endelevation of Fig. 6.

Fig. 11 is aside elevation of an enlarged fragment of my dumping mechanism asapplied to the depending system of-double-rope tramways. Fig. 12 is anend elevation of Fig. 11. Fig. 13 is a side elevation of a modificationof attaching the bucket to the dumping-actuating mechanism. Fig. 14 isan end elevation of Fig. 13. Fig. 15 is an enlarged side elevation of afragment of the top end of the bucket-pendant; and Fig. 16 is asectional View of the guide-rails roller, arranged so that one half canrotate in one direction and the opposite half can rotate in the oppositedirection.

Similar figures of reference refer to similar parts throughout theseveral views.

Referring to the drawings, the numeral 1 designates the traction-rope,and 2 the track rope or rail of a double-rope tramway, and hereinafterthe traction-rope will be designated by the numeral 1, whether itrelates to the single-rope or double-rope system.

The numeral 3 designates a terminal, a fragment of the track-rope 2being shown connecting to the track-rail 2. The traction-rope 1 ispositioned above the track-rope. Gonsequently the dumping deviceillustrated in Figs. 1, 2, 3,4, 6, 7, 8, 9, and 10 is adapted for use onthe overhead system of double-rope tramways. The terminal 3 is a timberstructure arranged and adapted to support the traction-rope and thetrack and bucket and the storage-bins of the dumping-station. Thedumping-station is always placed at the discharging end of the tramway;but on tramways for mines in mountainous countries it is usual to placebucket dumping mechanism at both the upper and lower terminals, as it iscustomary to convey coal and supplies up to the mine, as well as totransmit the ore down from the mine. Consequently my dumping device maybe applied to or be a part of both Sometimes branch tramway-lines areconstructed that connect to the main line of a tramway, inwhich case itis necessary to have bins and (lumping mechanism at the connecting-pointof the main and branch li nes,and it may be desired to discharge loadedbuckets at some particular point in a tram-line between the terminals.My dumping device is particularly adapted for the last two uses.

The terminals of tramways are usually housed in a suitable building; butone of the features of my dumping device and terminal is that thetrack-ropes and dumping guiderails and mechanism are preferablysuspended from above, and this enables me to so construct the frameworkthat the side timbers 5 beams, the timber 9 the plate, 1.0 the rafters,

onlya fragment of which is shown, and 11 the flooring of a buildingthat'at the same time constitutes the terminals of a tramway and thesupporting structure of my dumping device.

Another very important feature of my dumping device, as illustrated, isthat when the supporting-framework is constructed as shown the entirespace between the sides or wall-posts of the structure is entirely clearof posts and timbers,enablin g a clear view of the incoming and outgoingbuckets or carriers, as well as an unobstructed floor-space forattendants to work in.

To the under side of the tie-beams 8 I secure three timbers 13, 1 1, and15, arranging them parallel to one another. To the under sides of thetimbers 13 and 14 I secure a number of depending vertical angle-ironbrackets 16, the lower end of which is turned at right angles to thevertical arm for a short distance and forms a horizontal rest 17 for themetal track 2, which is a continuation of the track rope around theterminal. The end of the horizontal arm 17 of the angle-iron bracket isprovided with a short vertical rib 19, which is positioned just farenough from the end of the bracket to allow the track 2 to rest 011 itand against the rib and be even with the end of the bracket, thusforming a step. The track rail rests on this step and is bolted by bolts20 to the rib. These brackets are positioned at suitable distances apartalong the dumping structure, and each bracket is supported by a strut21, which is secured at one end to the timber Band at its opposite endto the lower end of the bracket.

Upon the track 2 the trolley 22 of the bucket or carrier is mounted, abucket being preferably shown in the drawings. This trolley comprisesthe housing 23 and the sheavewheels 24. y The sheave-wheels rest and runon the track or track-rope. A pendant 25 is pivotally attached to oneside of the trolley, and a bucket 26 is pivotally secured between thelower ends of the pendant, so that it can be tilted or dumped betweenthe ends of the pendants. In the overhead system, such as is illustratedin most of the figures of the drawings, the rope-clip 27, that propelsthe trolley, is secured to the trolley at one end and to thetraction-rope 1 at the opposite end,

while in the depending system the clip 27 is attached to thebucket-pendant or to some gripping mechanism attached to the pendant ofthe bucket at one end and to the tractionrope at its opposite end, asshown in Figs. 11 and 12.

To the side of the timber 15, opposite from the track 2, I secure anumber of verticallydepending standards 28. To the under side of thetimber 15 I secure at predetermined points a lug-plate 29, to which Ipivotally secure one end of a depending rod 30 by a pin or bolt 31. Thelower end of this rod is pivotall y secured to lug-plates 32, which forman integral part of a doubletrack-supporting yoke This yoke stands inavertical position and is provided with two oppositely-disposedintroverted lips 34 and 235, which are placed far enough back from theends of the yoke to form a step for the guide-rails and 37 to rest on.These guide-rails are secured to the lips of the yoke and also to thedepending standards by bolts or rivets. The guiderails are preferablypositioned in a vertical plane, one over the other and at a short spaceapart, which forms a slot 38 between them into the space formed betweenthe guide-rails and the back of the yoke. These guide-rails arepositioned wherever it is desired to automatically dump a moving bucket.Their front and terminal ends are arranged in a horizontal plane justbelow the-pivotal pin, that connects the pendant to the trolley and onthe side of the pendant farthest from the trolley. Their front ends 30are placed close enough to the rail and to the path of the pendant toreceive between them a spool 40,which is normally held against the sideof the pendant by the bucket, as will be fully explained hereinafter.The guide-rails at a short distance from their front ends are providedwith a short offset curve 40; but from this curve they extend alongparallel with the track 2, but far enough from it so that they are outof the path of the spool the remainder of their lengths. Consequentlythe spool, should it pass the entrance end of the guide-rails, isentirely clear of them and cannot become connected to them as it passesby them. The guide-rails are arranged in this manner in order to allowtheir spool-entrance end to be sprung aside whenever it is desired toallow a loaded or empty bucket to pass Without dumping it. done by meansof a rod 41, which is pivotally connected at one end to cars 42, thatare formed on the back'of the yoke by a pin 43. The opposite end of therod 41 is pivotally secured to one end of a lever 44, on the oppositeend of which a handle is formed. The lever is pivotally connectedintermediate of its ends to the slotted end of a bracket 45, which issecured to a support 46, that is secured to the side posts of theframework.

, From the bracket an arm projects close to the handle of the lever andinto the plane the lever moves in, and pin-holes 47 are formed in thelever at predetermined points, and a locking-pin 48 is fitted to them.The lever and red are arranged so that when they are moved in onedirection of their operative movement they will move the entrance to theguide-rails into the path of the spool of the pendant, so that it willenter the slot between them, and when moved to the opposite direction oftheir operative movement they will spring the entrance ends of theguide-rails back out of the path of the spool, as shown at 48 in Fig. 3,in which case the spool will pass the guide-rails and the bucket willnot be dumped. From the curved portion 40, of the guide-rails Iconstruct the remainder of the length of the rails for automaticallydumping a bucket as follows: The guide- This is the bucket, as will beexplained fully hereinafter. They are then bent to extend straight orhorizontally with the track 2 for a distance suflicient to hold thebucket in a dumped position until it fully discharges its contents whilemoving. The rails are then curved upward to the same height as at theentrance end and then curved to terminate in a straight portion. Theupward inclination of the rails allows the spool to travel back to itsnormal position against the pendant of the bucket. These bucket-dumpingguide-rails are positioned over storage-bins 46 which are built in thefloor of the supporting structure underneath the point where the bucketsare to be dumped, and as many bins and dumping guide-rails may be placedalong the terminals or along a tram-line at points where it is desiredto dump ore as required, or they can be arranged in continuous orderclose together. When dumping a standing or stationary bucket, however,the tracks are made straight and parallel with the track 2 from one endto the other, the curve used in the rails for dumping a moving bucketbeing dispensed with, and the rails lie throughout their length in thepath of the spool. In order, however, to dump a stationary or standingbucket, I employ a slightly-different mechanism from that employed tomove the entrance end of the rails out of the path of the spool. Theguide-rails for dumping a standing bucket are made shorter than theguide-rails for dumping a moving bucket and may also be placed insuccessive order over separate bins or, if desired, over a continuouslong bin at any point in the length of the tram. *When dumping astationary bucket, it isnecessary to first release the clip or grip fromthe bucket or traction rope Z, as this rope runs continuously. I do notillustrate means for accomplishing this, as it does not form any part ofmy present invention. In dumping a stationary bucket the spool and chainare pulled out from the bucket-pendant to dump the and in order to pullthe spool and chain after the spool has entered the slot between the.rails I secure the straight guide-rails, which are short and light ofweight, to two yokes 33, each of which is attached to one end of twolevers 47 and 47 the yokes being secured to the rails near theiropposite ends. These levers are secured at their opposite ends to ashaft 47 which is supported in the ends of depending hangers 47 that aresecured to an overhead timber 47 attached to the supporting structure.The depending brackets are positioned to enable the levers to be movedfar enough to pull the spool and chain far enough to dump the bucket, asindicated by the dotted lines in Fig. 7.

An u pwardlyprojecting arm 47 is secured to the shaft 457 to the freeend of which a rope 47 is attached, which is preferably carried over anidlersheave placed over the dumping mechanism to a position where it canbe operated either by an attendant or by some suitable means.Consequently whenever it is desired to dump a bucket that is dumpinglyconnected to the guide-rails it is only necessary to pull the rope,which will move the levers to move the rails and spool and chain to dumpthe bucket, as will be explained hereinafter. A weight 47 is attached bya rope 47 to the arm 47 and holds the dumping device in its normalposition, where it is limited by stops 47 on the levers 4.7 and 47 whichcontact with the hangers 47 r The spool is rotatably mounted on a pin50, which is secured thereto, upon one end of which is formed a loop 51.In Fig. 16 I show the spool made in two halves transversely through itslength, so that each end may rotate independent of the other, thisarrangement being adapted to the swinging track shown'in Figs. 6 and 7,in which arrangement, when the guide-rails are swung out, as shown indotted lines in Fig. 7, one half of the spool will rotate on the lowerrail and the other half pin that connects the pendant to the trolley. 1

This curved aperture enters the front side of the casting at the top ofthe pendant through the center of a hub 54 and curves downward and comesout at the bottom of the casting between the side bars of the pendant.(See Fig. 8.) To the bottom of the aperture I secure one end of a casing55, which I preferably employ to form a covering and conduit for thechain, the opposite end of which is connected by a clip 56 to an angledcross-bar 57, which extends across the pendant of the buckets and issecured thereto. The lower terminal end of the casing is curved,preferably, toward the track and trolley side of the tram-line and isflared outward. The chain passes through the casing and extends over andaround the bucket and is connected to a bucket-locking bar 58, thatextends from the lower ends of the bucket-pendant and extends down thesides and under the bottom of the bucket. The lower end of the pendantsabove the points of their pivotal connection with said bucket isprovided with a short rearward extension 59, to the end of which theends of the locking-bar are pivotally secured. To each of the oppositeends of the bottom of the bucket I secure, downwardly and slightlyrearwardly, brackets 60, each of which is provided with an angular slotconsisting of a subtantially horizontal portion 61 and a substantiallyvertically inclined portion 62, through which the locking-bar passes.When the bucket is in its normal upright po- 1 sition, the locking-barrests'in the end of the horizontal portion 61 of the slot and locks thebucket against accidental movement; but when the bucket is turned over,as shown in dotted lines in Fig. 9, the locking-lever moves to theopposite end of the horizontal slot 61 and along the vertical-slot 62.

In Figs. 11 and 12 I illustrate this bucketdumping mechanism adapted tothe depending traction-rope system of double-rope tramways. In thissystem the traction-rope and the clip are positioned below the track 2,and the clip is secured either manually or automatically to a cross -bar63 of the pendant. I illustrate the clip secured to a plate 64, thatforms a part of the cross-bar 63. A clip 65 is secured to this plate andcross-bar and supports the upper end portion of the chain-casing, whichin this system extends only from opposite the traction rope and clip tothe angled cross-bar 57, which is located in the same position as inFigs. 9 and 10. The top end of the chain-casing is curved at rightangles to the vertical portion and to the front side of the pendant andbracket and is flared outward. The lower terminal end is like theterminal shown in Figs. .9 and 10. The bucket may be provided with thesame locking and chain attachment device as Figs. 9 and 10, or, ifdesired, in place of this a simple loopclip 66 may be secured to thebottom of the bucket, as shown in Figs. 11 and 1.2, and the chain may beattached to it.

In Figs. 13 and 14 I show a m'odificationof the arrangement of thebucket dumping mechanism. This modification,as illustrated, is adaptedto the overhead system, but can be applied to the depending system.(Shown in Figs. 11 and 12 as well.) This modification consists ofextending the chain casing down one of the sides of the pendant and ofsecuring it to the side of the pendant by clips 67. The upper end of thechain-casing extends to a hub 68, formed on the casting at the apex ofthe pendant, the casting in this case being open below the hub andhaving only a web 69 at the back, thus allowing the casing to extend upto the hub, which is provided with an aperture similar to that shown inFig. 8. The lower terminal end of the casing is curved and flaredoutwardthe same as in the other views. The chain extends down the sideof the pendant to the end of the bucket, where it is connected to asegment of a sheave 70, in the tread of which it is seated and secured.This segment of a sheave is riveted to the end of the bucket concentricto the pin 69 of the bucket, to which the end of the pendant ispivotally secured. From the lower edge of the segment an arm 7 0'projects, which forms a stop, and when the bucket is turned to dump itthe stop engages the adjacent end of the pendant, thus preventing thebucket from being turned completely over. A stop 71 is also shownattached to the bucket in Figs. 2, 11, and 12. I preferably use a bucketthat is overbalanced on one side and preferably place the overbalanceside on the same side of the pendant as the track 2 and tractionrope Iand arrange the dumping to the rearward or ovcrbalanced side, so thatthe overbalanced weightof the bucket and of its load is on the chain andholds the spool against the front side of the pendant. The stops and thearrangements shown in Figs. 9 and 10 prevent the bucket from passingover the center.

The operation of myimproved dumping device is as follows forcontinuously-moving buckets: As the bucket is attached to thetraction-rope and is moved by it over the trackrope and track 2 withoutstopping the spool when the bucket arrives at the guide-rails enters theslot between them and as the bucket continues right along the spool runsdown the inclined slot between the rails, which is of suiiicient lengthto pull the spool and chain far enough to tip the bucket into fulldumping position by the time the spool has reached the lower straightportion of the track, along which it is pulled by the movingbucket,which holdsjthe bucket in its turned-up dumping position while itis traveling over the lower stralght portion of the rails, thus givingit ample time in which to discharge itself. The spool then runs up theinclined slot and out of, the rails thus allowing the bucket to rightitself practically as gradually as it is tilted at the opposite end ofthe guide rails. The

' bucket is thus tilted, dumped, and righted into its normal positionwithout sudden shock or jar or noise and without stopping it in itscourse around the tramway-line, while for stationary buckets that havebeen detached from the traction-rope it is only necessary to operate therope to move the short straight guide-rails back, as above described andas shown in Figs. 6 and 7.

My invention is simple, durable, and easily applied to tramway-lines atsmall expense.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
